Question

If wattless current flows in the AC circuit, then the circuit is (A) Purely Resistive circuit (B) Purely Inductive circuit (C) LCR series circuit (D) RC series circuit only

Tardigrade Admin · Accepted Answer

Purely Inductive circuit θ=(π/2) cos (π/2)=0 Average power =0

Q. If wattless current flows in the $A C$ circuit, then the circuit is

Purely Resistive circuit

Purely Inductive circuit

LCR series circuit

RC series circuit only

Purely Inductive circuit
$θ = \frac{π}{2}$
$cos \frac{π}{2} = 0$
Average power $= 0$
